AUTOMATIC TRAIN TRACK-TRIP.

To all whom it may concern Be it known that I, JUnon S. ALLEN, a citizen of the United States, and a resident of the city of New York, borough of Manhattan,` in the county and State of New York, have invented a new and Improved Automatic Train Track-Trip, of which the following' is a full, clear, and exact description.

My invention has for its object to provide an automatic t 'ain track trip having a hollow post in which a shaft is jonrnaled, a hood being secured to the top of the shaft and having depending lugs which engage stops on the post for limiting the movement of the hood and the shaft. The hood ex tends outward `from the shaft and has a depending peripheral member for protecting the stops and the lugs from the weather.

Secured to the hood Athere is an extending arm which is adapted to be engaged by a contact member carried by a locomotive or Additional objects of the invention will appear in the following complete specificavention is disclosed.

In the drawings similar reference characters indicate corresponding parts in all the views in which- Figure 1 is an elevation showing the signal post; Fig. 2 is an enlarged sectional elevation of the top of the signal post, and Fig. 3 is an inverted sectional view of Fig. 2 showing the means for checking the rotary movement of the hood relatively to the hollow post.

By referring to the drawings it will be seen that a hollow post 5 is provided which is disposed on a base G, which rests on a casing 7, this casing 7 if desired, being disposed below the level of the ground. In the hollow post 5 there is journaled a vertical shaft 8, secured lto which there is a beveled gear 12 with which meshes a beveled gear 13 secured to a shaft 14.

The shaft 8 has threaded portions 48 and 49, a bearing member being provided and having a threaded orifice which meshes with the thread 48 in the shaft 8, a bearing member 51 being also provided this bearing member 51 having a threaded orifice which meshes with the thread 49 of the shaft 8. Nuts 52 are provided for holding the bearing members 50 and 51 in position.

Disposed in the hollow post 5 there is a Specification of Letters Patent.

hollow member in which is disposed a bearing member 54 lmving an upper portion 5o and a lower portion 56. As a means of securing the hollow member 53 and the bearing member 54 in position, I provide a set screw 57, which extends through an orifce in the hollow post 5 and which meshes in threaded orifices in the member 53, and thc bearing member 54.

Bearings 58 are disposed at the bottom of the lower portion 5G of the bearing member 54, bearing balls 59 being disposed between the bearing member 50 and the said bearing 58. A bearing G0 is disposed above the upper portion of the bearing member 54, and bearing balls 61 are disposed between the bearing member 51 and the said bearing G0.

It will be understood that the bearing member 50 and the nut 52 are disposed in position when the member 53 and the bearing member 54 are disposed in the hollow post 5, after which the bearing member 51 and its nut 52 are disposed in position, the bearings 58 and (50 and the bearing balls 59 and 61 being disposed in position at the proper time.

Meshing with the inner thread at the top of the hollow member 53, there is a casing member (32, this casi ng member 62 having an opening G3 through which the shaft 8 is disposed. The casing member 62 serves to inclose the top of the bearings to prevent dust from settling down therein. Secured to the shaft 8, above the bearings, there is a hood 64, this hood 64 having a top G5, the top 65 having an opening (SG theretln'ough, this opening (S6 being angular in cross section, so that the angular' portion (S7 of the shaft 8 may be disposed therein as a means of rotating the hood G4 with the shaft 8. The sides (38 of this hood (S4 diverge downwardly a considerable distance with their lower portion G9 forming an apron within which extends the periphery 70 of the shield 71, this shield 71 being disposed around the hollow post 5 and being secured thereto, the sides of the shield 71 diverging upward with the periphery 70 of the shield 71. disposed within the portion 69 of the hood G4, as has been stated.

In the post 5 there are threaded orifices 72 in which mesh the threaded portions 73 of the studs 74; these studs 74 are provided for engaging the wings or lugs 75 which are secured to, and which depend from the web 7G of the hood 64. Secured to the top 65 of the hood 64e there is a signal blade 77, this signal blade 77 extending from one side of the hood 6d, an arm 78 being provided which is also secured to the top 65 of the hood this arm 78 extending from the other side of the hood. This arm 78 is provided for engaging a member on the cab of a locomotive for operating any approved mechanism on the locomotive for sounding a signal, applying the brakes, or cutting off the power of the locomotive.

As a means for holding the top G5 of the hoodL Get in position on the shaft 8, l provide the top of the shaft 8 with a threaded portion S0 with which meshes a nut 8l, the nut S1 pressing down against the top 65 of the hood. On this threaded portion 80 of shaft 8 l also propose to mount a lantern 82, so that when the arm 7S is extended in the direction of the track, and the signal blade 7l' extends in a direction away from the tracl-r, the lantern 82 will be disposed so that the red glass 83 will exhibit the danger signal, butI when the shaft is rotated and the arm 78 and t-he signal blade TT are disposed substantially parallel to the track, the lantern 82 will be turned to exhibit a white or green glass, as may be desired. lt will be understood that by the rotation of the shaft la and through the gears l2 and 13, the shaft 8 may be rotated as desired.

llaving thus described my invention, l

f claim as new and desire to secure by Letters Patent:

l. ln an automatic train track trip, a hollow post, a shaft disposed in the post and extending through the top of the post, a hood secured to the upper end of the shaft and extending` down and spaced from the post, a horizontal web in the hood and secured thereto, there being an opening in the web through which the post is disposed a depending lug on the web, a stop on the post for engaging the depending lug, and signal means secured to the hood.

2. ln an automatic train track trip, a hollow post, a. shaft disposed in the post, a hood secured to the upper end of the shaft and disposed over the post,a lug within the hood and disposed above the bottom of the hood a stop on the post adapted to be enM gaged by the lug, a shield secured to the hollow post, the side of the shield diverging upward with the periphery of the shield disposed wit-hin the hood and an arm seing surfaces, a hood secured to the shaft` above the hollow post and extending downward at the outer side of the hollow post, studs secured to the hollow post, wings on the hood engaging the studs for limiting the movement of the hood, and the shaft relatively to the post, a shield secured to the post the sides of the shield diverging upwardly, and wit-hin the hood, and a signal member mounted on the hood.

e. ln an automatic train track trip, a hollow post, a bearing member having upper and lower bearing surfaces, the bearing member being secured to the post and having a central opening therethrough, a shaft disposed in the hollow post, and having threaded portions, the shaft extending through the opening, bearing members having threaded orifices meshing with the threads on the shaft, land cooperating with the said bearing surfaces, a hood secured to the shaft above the hollow post and extending downward at the outer side of the hollow post, st-uds secured to the hollow post,y wings on the hood engaging the studs for limiting the movement of the hood and the shaft relatively to the post, a shield secured to the post, the sides or the shield diverging upwardly, and within the hood, and a signal member mounted on the hood.

ln witness whereof I have signed my name to this specification in the presence of two subscribing witnesses.
